Installation of the present invention, work and using process:
With the solar water heater is example
Water container is communicated with by connecting tube and the water filling solenoid valve that discharges water, and joins at the discharge water bottom and the water pipe of solenoid valve of water filling, and faucet and running water pipe are installed on water pipe, and water injecting electromagnetic valve is installed on running water pipe, in the lower end of water pipe the solenoid valve that discharges water is installed.Water container and the water filling solenoid valve that discharges water is installed in the top of outdoor building thing.Running water pipe, water injecting electromagnetic valve, faucet and the solenoid valve that discharges water are installed in indoor.
Water container is a hot water tank, the automatic water level sense switch is installed in the water container, be used to monitor water position status, when water level is low during to designated water level, the start switch water filling power of electromagnetic valve that discharges water carries out moisturizing, when reaching designated water level, the level sensor switch cuts out automatically, closed the discharge water power supply of solenoid valve of water filling, made closed electromagnetic valve, stopped supplying water.
Under water container water level normal condition, can emit hot water by faucet, when emitting hot water, need to connect the electric switch that discharges water, the water filling solenoid valve that discharges water is opened.
When by water injecting electromagnetic valve after the water container water filling, then turn-off the discharge water switch of solenoid valve of water filling, valve opening set on the water filling solenoid valve return that discharges water, blow-down pipe and spool communicates, and the valve opening of the solenoid valve that discharges water also communicates with offlet, blow-down pipe and atmosphere are connected, and are subjected to the effect of water gravity, and the water in the water pipe is discharged by offlet, then the water in the Hu Wai water pipe is discharged automatically, make to be empty state in the water pipe, therefore, avoided the water in the water pipe to be frozen and destroy water pipe and solenoid valve.
During water emptying in water pipe, the water in the valve pocket makes the water in the valve pocket release by drain pipe by the return-air hole return-air, thereby avoids discharge water water in the solenoid valve of water filling to freeze and destroy valve body.
The discharge water working procedure of solenoid valve of water filling: when in the electromagnetic coil of electromagnetic driver, not having electric current to pass through, be subjected to the effect of spring, the tight pressing of valve head and valve seat, the water in the water container can not be discharged, and blow-down pipe and valve opening are channel status.When water filling discharges water solenoid valve when having electric current to pass through, be subjected to the adhesive effect of electromagnetic driver, with armature to the adhesive of electromagnetic coil end, the pulling valve head breaks away from valve seat, water in the water container promptly flows downward by water pipe, supply with water by faucet and use, blow-down pipe and valve opening stagger simultaneously, and air can't enter into water pipe from blow-down pipe.
The working procedure of solenoid valve discharges water: when not having electric current to pass through in the driver of the solenoid valve that discharges water, be subjected to the effect of spring, valve opening and offlet are channel status, and the water in the water pipe can flow out by discharge water solenoid valve and offlet.When having electric current to pass through in the electromagnetic coil of the solenoid valve that discharges water, the electromagnetic driver adhesive armature, the pulling spool makes offlet by valve opening and water pipe path, and the water in the water pipe can flow out from offlet.
During water filling, water filling discharges water solenoid valve in opened condition in water container, and the solenoid valve that discharges water is a closed condition.
When discharging water from water pipe and water container, water filling discharges water solenoid valve in opened condition, and the solenoid valve that discharges water is a closed condition.
When the water emptying state in the water pipe, discharge water solenoid valve and the solenoid valve that discharges water of water filling all is closed condition.
Advantage of the present invention
1, can realize water emptying in the water pipe, prevent to freeze and destroy or shutoff water pipe and the water filling solenoid valve that discharges water.
2, the water emptying in the water pipe realizes by solenoid valve, thereby needn't the very important person go up eminence, avoids the generation of security incident.
3, when not carrying out in water container water filling or discharging water, solenoid valve is disconnected power supply, thus consumed power not.
Device of the present invention suits to install and use on solar water heater, also can install and use in other liquid line emptying is antifreeze.
